Honestly, this sounds like an attempt to avoid being named in any lawsuits related to the collapse of Bitcoinica and/or being pursued by a liquidator for the recovery of funds.
Possibly. He certainly did his best to avoid being named in lawsuits (who can blame him?):
I contributed 5,000 BTC and talked to the creditors regularly exactly because I wanted to avoid any lawsuits against me.
Anyway, I will now stop selectively quoting Zhou from the conversation I had with him this week. If Zhou agrees, I would be happy to make the entire conversation public.
